A topped golf shot is caused by a player hitting the ball above its equator. Compare this to a thinned shot where the leading edge of the club face catches the ball below the equator but not low enough to make full contact.
Tennis shots. In tennis, there are a variety of types of shots (ways of hitting the ball) which can be categorized in various ways. The serve is the opening shot of a point. Groundstrokes are hit after the ball has already bounced, and can be either forehands or backhands depending on which direction the racket is swung relative to the body. A lob is a groundstroke hit well over the head of an opponent who is positioned at the net.
